    Priority: Major  (was: Minor)


> maxbufsize doesn't include JVMROUTESZ

>                 Key: MODCLUSTER-621
>                 URL: https://issues.jboss.org/browse/MODCLUSTER-621
>             Project: mod_cluster
>          Issue Type: Bug
>          Components: Native (httpd modules)

>     if (mconf->maxmesssize)
>        maxbufsiz = mconf->maxmesssize;
>     else {
>        /* we calculate it */
>        maxbufsiz = 9 + JVMROUTESZ;
>        maxbufsiz = bufsiz + (mconf->maxhost * HOSTALIASZ) + 7;
>        maxbufsiz = bufsiz + (mconf->maxcontext * CONTEXTSZ) + 8;
>     }
>     if (maxbufsiz< MAXMESSSIZE)
>        maxbufsiz = MAXMESSSIZE;
>     buff = apr_pcalloc(r->pool, maxbufsiz);
> {code}
> It looks like {{maxbufsize}} will never include the {{9+JVMROUTESZ}} since it overwritten with new value in following line. Is this a problem?
